Python Python Basics (2015) Letter Game App Even or Odd Loop

Please spot my mishap, my task doesn't pass

I've ran this script locally and it outputs five random numbers with 'is even' or 'is odd' just fine. Only, in the editor, it keeps saying ' Oops! It looks like Task 1 is no longer passing' - which is the import random task. It is, so I'm guessing what more I should alter to let this task pass.

even.py
import random

start = 5

def even_odd(num):
    # If % 2 is 0, the number is even.
    # Since 0 is falsey, we have to invert it with not.
    return not num % 2

while start > 0:
    num = random.randint(1,99)
    if even_odd(num):
        print ('{} is even').format(num)
    else:
        print ('{} is odd').format(num)
    start -= 1

The issue is that you are calling the format method on the print function rather than the string argument passed to it. If you move the format call like this:

import random

start = 5

def even_odd(num):
    # If % 2 is 0, the number is even.
    # Since 0 is falsey, we have to invert it with not.
    return not num % 2

while start > 0:
    num = random.randint(1,99)
    if even_odd(num):
        print ('{} is even'.format(num))
    else:
        print ('{} is odd'.format(num))
    start -= 1

Then your code will work fine.

Ah, there you go! Thank you. Since my current development environment is Python 2.x, I am not used to working with format yet. Well spotted, it passes now!
